Do you mean after attempting to import the definition files?

Yes.

I installed PP-2014 and (re-)installed EZskin and there were no definition files including the custom made ones I already made for my hybrid figures. (They have new object names and custom material zones)

Had to manually copy and paste in the appData but even then only the "default" definitions showed up. (V2,V3,V4,M2...etc)

As I said, not such a big problem as I'm constantly tweaking shaders so I have to use my own material files instead of EZSkin anyway.
